7Semi VCNL4030X01 Proximity and Ambient Light Sensor Breakout with I2C Interface, 940 nm IRED and Qwiic Connector for Easy Integration
The 7Semi VCNL4030X01 breakout board brings a proximity sensor, an ambient light sensor and a high-power infrared emitter together on one compact module. The sensor is built on a CMOS process and integrates photodiodes, amplifiers and analog-to-digital converters in a single chip. The board runs on 3.3V or VIN, communicates over I2C at address 0x60, and includes a Qwiic connector. You can connect it to compatible microcontroller boards without soldering.
The 16-bit ambient light sensor suits both dark enclosures and high-transparency lens designs. The proximity function uses a 940 nm IRED and supports 12-bit or 16-bit output data. Both functions have programmable interrupts with separate high and low thresholds, so your microcontroller can stay idle until something changes. This makes the board well-suited to display dimming, touch-screen locking, presence detection, and collision sensing in robots and toys.
Key Features
- Integrated Sensing: Proximity sensor, ambient light sensor and high-power IRED in one package.
- 940 nm IRED: Immune to red glow, with programmable IRED sink current.
- Selectable Proximity Resolution: 12-bit or 16-bit PS output data.
- Cross-Talk Cancellation: Intelligent cancellation reduces the cross-talk phenomenon.
